Abstract: This paper proposes a new topology for a X-/Ka-band shared-aperture phased array to achieve high aperture utilization. The unit cell of the shared-aperture array consists of one X-band ...
Abstract: In this paper, a 4 × 4 wideband linearly polarization (LP) antenna array is proposed by using planar dual-arm spiral structures. Wideband balun structures, composed of microstrip line-fed ...
